CONNECTING TTHE SSYSTEM
The development system box contains a development system, CD, USB cable and
serial cable.
The first thing to do is to take the system out of a box. Unpack the USB cable and
connect it to the PC. Please use USB ports from the back of the PC, with direct con-
tact to the motherboard.
Connect the USB cable to the dsPICPRO board.
The PC will start the procedure for installing the USB driver for the on-board USB
2.0 programmer. Follow the procedure from the document ‘ Installing Driver for
USB programmer’ and install the USB driver.
Copy dsPICFLASH2.exe file to the folder of your choice. You can find this file in
the dsPICFLASH folder on the CD.
Run and use dsPICFLASH2.exe as explained in the document ‘dsPICflash pro-
grammer’.
After these 5 steps, your dsPICPRO is installed and ready for use. You should try
to read a program from the chip or to load an example from the examples folder.

INTRODUCTION
The dsPICPRO development system is a full-featured development board for
Microchip dsPIC microcontrollers. It has been designed to allow students and engi-
neers to easily exercise and explore the capabilities of dsPIC microcontrollers. It
allows dsPIC microcontrollers to be interfaced with external circuits and a broad
range of peripheral devices, allowing the user to concentrate on software develop-
ment.
Figure 1 illustrates the development board. On a silkscreen, there are identification
marks beside each component. These marks describe connections to the microcon-
troller, operation modes, and provide some useful notes. The need for additional
schematics is minimized as all the information is printed on the board.

SWITCHES
SWITCHES
The dsPICPRO development board features many peripherial devices. In order to
enable these devices before programming, you need to check if appropriate jumpers
or switches have been properly set.
Switches are devices that have two positions - ON and OFF, which have a role to
establish or break a connection between two contacts.
The first switch, SW1, is used to enable LEDs connected to ports RB_L, RB_H,
RD_L, RD_H, RF and RG. For example, if switch RB_L is OFF, all RB lower
LED’s will be turned off.
The switches SW2 and SW3 are used to enable connections between various
peripheral devices and microcontroller pins.
For example, SW2 and SW3, enables a connection between the microcontroller
pins and temperature sensor, programmable gain amplifier (PGA), real time clock
(RTC), RS-485 communication etc.

JUMPERS
Jumpers, like switches, can break or establish a connection between two points.
Beneath the plastic cover of the jumper is a metal contact, which makes a connec-
tion when the jumper is placed between two disconnected pins.
Jumpers are used as a selector between two possible connections using a three pin
connector. As illustrated in Fig. 3, middle connector can be connected to the left or
right pin, depending on the jumper’s position.

If there is already MCU Card
placed on dsPICPRO, you must
remove it by slowly pulling it up.
Label on the MCU Card must
be at the upper-left corner as it

The microcontroller’s pins are routed to various peripherials as illustrated in Fig.5. All ports have
direct connections to Direct Port Access connectors. Such connectors are typically used for con-
necting external peripherials to the board, or for providing useful points for connecting digital
logic probes.
All ports are connected to LEDs, push-button switches and pull-up/down resistors , which allow
for easy digital pin state monitoring and testing.
Some of the pins are connected to other peripherials such as the DS1820 temperature sensor, RS-
232 communication, LCD, etc.

POWER SSUPPLY
As a power supply source, users can select either a regulated supply from USB
cable (default) or an external non-regulated power supply.
In case of the USB power supply, the system sholud be connected to a PC using the
USB programming cable and jumper J1 should be set in the upper position.
In case of an external power supply, the dsPICPRO board produces +5V using an
LM7805 voltage regulator. The external power supply can be AC or DC, with a
voltage between 9V and 16 V, and jumper J1 should be set in the lower position. In
Fig. 7 you can see the USB (left) and power supply (right) connectors.

ON-BOARD USB PROGRAMMER
There is no need for the use of external
equipment during programming, as the
dsPICPRO development system has its
own on-board USB programmer.
All you need to do is connect the system
to a PC using the USB cable. Then, load
your program into the microcontroller
via the dsPICFLASH2 programming
software, which is supplied with the
board.

LED’S
Light Emitting Diodes (LEDs) are the most commonly used components, usually for
displaying pin’s digital state. The dsPICPRO have 48 LEDs that are connected to the
microcontroller’s ports RB low, RB high, RD low, RD high, RF and RG.
LIGHT EMITTING DIODES
Figure 11.
Light Emitting Diodes
Each group of eight LEDs can be enabled or disabled using switch SW1, as shown
in Fig. 11.
Fig. 12. illustrates the connection of a LEDs to lower PortB of the microcontroller.
A resistor is used in series with the LED to limit the LED's current. In this case the
resistor's value is 1K.

LED’S
All LEDs from one port are connected to a common point through these resistors,
which can then be connected or disconnected to ground by the corresponding switch
on SW1. The LEDs are enabled when connected to a ground and will display the
state of the corresponding microcontroller pin; otherwise the LEDs will always be
off, no matter what the pin state is, because no current can flow through it.

PUSH BBUTTONS
PUSH BUTTONS
Figure 13.
The dsPICPRO has 48 push buttons, which
can be used to provide digital inputs to the
microcontroller's ports. There is also one
push button that acts as a RESET (Figure
13).
Reset button
Figure 14.
Push buttons
Jumper J10 (zoomed on the figure
14) determines whether a button
press will bring logical zero or log-
ical one to the appropriate pin.
Buttons connection to ports RB_Low, RB_High, RD_Low, RD_High, RF and RG
is shown in Fig. 15. In this example, the buttons are connected to +5V. In order to
detect a button state, pull-up or pull-down resistors should be used.

BUTTONS
In the case of Fig. 17 the pull-
down resistor pulls the microcon-
troller port pin to ground when the
button is not pressed. A button
press causes the port pin to be
connected to +5V (J10 is in the
upper position). Thus, only when
the button is pressed will the
microcontroller sense a logical
one; otherwise the pin state will
always be logical zero.
In the case of Fig. 16 the pull-up
resistor pulls the microcontroller
port pin to +5V when the button is
not pressed. Abutton press causes
the port pin to be connected to
ground (J10 is in the lower posi-
tion). Thus, only when the button
is pressed will the microcontroller
sense a logical zero; otherwise the
pin state will always be logical
one.

When GLCD is on place you can

board.
GRAPHIC LCD
The Graphic LCD (GLCD) allows advanced visual messages to be displayed.
While a character LCD can display only alphanumeric characters, a GLCD can be
used to display messages in the form of drawings and bitmaps. The most common-
ly used graphic LCD has a screen resolution of 128x64 pixels. Before a GLCD is
connected, the user needs to set jumper J23 (Fig. 18) to the right-hand position. The
GLCD’s contrast can be adjusted using potentiometer P1. Jumper J23 and poten-
tiometer P3 are placed on the area of the GLCD. When GLCD is on place you can
adjust contrast through the hole from other side of development board.

When using a character LCD, it should be placed on the GLCD connector. Since
GLCD connector has 20 pins and the character LCD has only 14 pins, special atten-
tion is required when placing the LCD. Otherwise the LCD can be permanently
damaged. The LCD must be placed in the marked position with two free pins to the
left and four free pins to the right. When you add or remove LCD be sure that the
power supply is off.

Before adding the LCD, set jumper J23 to the left-hand position, labeled as CHAR.
The LCD's contrast can be adjusted using potentiometer P1. Jumper J23 and poten-
tiometer P3 are placed on the area of the GLCD. When GLCD is on place you can
adjust contrast through the hole from other side of development board.
